Omega Seamaster Diver 300M No-Date Master Co-Axial 42 Stainless Steel / Black / Bracelet Ref. 210.30.42.20.01.010

The OMEGA Seamaster Diver 300M 210.30.42.20.01.010, introduced in 2024 as part of the modern Diver 300M range that has defined OMEGA’s professional dive watches since 1993, presents the collection’s contemporary stainless steel configuration on a metal bracelet. The model combines familiar Seamaster design elements with updated materials and current Master Chronometer standards. The 42 mm stainless steel case is paired with a black oxalic anodized aluminium bezel ring featuring a diving scale filled with white Super-LumiNova. Water resistance is rated to 300 metres, and the case is fitted with a domed sapphire crystal with anti-reflective treatment on the inside. The dial is executed in black aluminium and laser-engraved with the Seamaster Diver 300M’s signature wave pattern. Skeletonised hands and applied hour markers are rhodium plated and filled with white Super-LumiNova, while the remaining dial markings, including the OMEGA logo and text, are transferred in white to maintain a clear, high-contrast layout. Power is provided by the OMEGA Co-Axial Master Chronometer Calibre 8806, a self-winding movement certified for precision, magnetic resistance up to 15,000 gauss, and a power reserve of approximately 55 hours. The movement is visible through the sapphire-crystal caseback. This reference is delivered on a brushed stainless steel mesh bracelet with clasp, reinforcing the model’s functional character while offering an alternative to the collection’s more common three-link bracelet and strap configurations.
